Question

A book sold 37,400 copies in its first month of release. Suppose this represents 9.2% of the number of copies sold to date. How many copies have been sold to date?

Round your answer to the nearest whole number.

Answer 1

406,522

Explanation:

It is given that 37,400 copies were sold in the first month and the percentage of this represent 9.2% of the number of copies sold to date.

Let's set up an equation:

9.2% · x = 37,400

Where x represents the total copies sold.

A percentage is that number over 100 in fraction form so, 9.2% = 9.2/100

0.092x = 37,400

/0.092 /0.092

x = 37,400/0.092

x = 406,521.73913

Rounded to the nearest whole number:

x = 406,522

So the total copies sold are 406,522.
